4. A 2-kg block is used to compress a spring of k=200-N/m by 50-cm. It is then released from rest. At the same time, a 1-kg bob that is tied to a 2-m long string is raised to an angle of 60 is also released from rest. If the two objects collide where the bob is at the lowest point in its swing, and do so without deformation, determine: a. The velocities of both objects the instant just after the collision (10pts) b. What is the tension in the string that the 1-kg bob hangs from at the instant just after the collision (10pts) Hint: Consider what path the bob is traveling along since it is tied to the string. c. To what angle the 1-kg bob will swing back to after the collision (10pts) The objects collide here, without 2-m deformation (Compressed 50-cm) k=200-N/m
